I was just given a new baking stone actually I am not even sure it fits my oven yet. My question is this do baking stones need to be "seasoned" in any way do you need to do something or can you just start baking with them?. Using a stone is very new to me as I have been using tiles for all these years.
I'd rinse it off just so any contaminents from the box are gone (dust, etc) and let it dry overnight. I've never had to "season" the stone, but I would recommend using parchment paper under your loaves for easy loading and unloading, and especially if you are working with cheese on your loaves.
Overall baking stones are fun, although I only use mine once in a great while. Don't forget a peel, which is pretty cheap at Bed Bath and Beyond if you want to go the budget route.
